lights and has for one of its objects the pro;

vision of an improved construction of abutment for sup orting the glass plates on the beams consisting of a plate ofmetal secured transversely of the beam, said plate having projections that extend through transverse slots formed in the beam, the ends of said projections being clenchedon the under side of the beam to hold the abutment in position.

Another object of my invention is the provision of an improved construction of transverse joint bar consisting of a base formed with holes to engage the bolts for holding the cap in place and provided with an upturned portion that serves as an abutment to hold the plate of glass above it in position. The two edges of the joint bar are provided with gutters that carry off the water of condensation and leakage. J

A further object of my invention consists in the provision of an improved construction. of cap consisting of an arched portion with its edgesbent backon themselves and having-strips of sheet lead secured thereto to form a water tight joint.

7 Still another object of my invention is the provision of an improved construction of I olt for securing the cap in place having its 7 lower end formed rectangular-in cross section and fitted in a similar shaped hole in the beam and its end riveted on the'under side thereof.

The construction of my improved roof or skylight will be described in detail hereinafter and illustrated in the accompanying drawings in-which Figure 1 is a longitudinal sectional view of a fragment of a roof involving my improvements, Fig. 2, a cross section on the line :vae of F ig 1, Fig. 3,'a similar view on the line yg of Fig. 1, and Fig. 4, a detail view of one of the abutment plates before being secured in position.

eral views.

A indicates the supporting beams for the roof on which are secured the beams 1 by means of lugs 2. The beams 1 are of the type shown and described in U. S. Letters Patent issued to me on March 3, 1908, No. 880,65st, being of the inverted channel beam type with their lowerends bent outwardly and upwardly to form drains 3 and with its top surface formed with a central'long1tud1 nal groove 4 to carry off any water that might leak through the joint between the with shallow 'rooves 5 in which are seated lengths of soft metal tubing 6 that act as the surface of the roof, sald tubes, as explained in the patent aforesaid, recelvlng the impression of the roughnesses on'the under side of the glass so as to makea water tight joint therewith to prevent rain water that might leak through the jolnts between the surface plates from creeping along the underside of the plates. At the lower end of each beam 1 are formed transverse slots 8 in the portion at each side of groove 4:. p

9 indicates a plate having lugs or pro ections 10 on its lower edge that engage slots 8, the ends of said lugs being clenched on the underside of the beam as shown at 10 to hold the plate in position, and to prevent any possibility of leakage through the slots 8 after the plate 9 is in position the clenched support the lower end of the surface plates.

12 indicates an arched portion between lugs .10 that is over groove 4: when the plate is in position as shown in Fig.3, so as not to obstruct the drain formed by said groove the joints between the roof surface and the caps to flow off.

13 formed with an upset portion 13 to engage the plate 9, a gutter or drain 14 extending downwardly from the inner edge of base 13 with its supporting wall formed vertical while its other edge is'bent downwardly on substantially a vertical plane as shown at 15, then backunder the beam 1 as shown at 1'6,

and then downwardly and secured to the In the drawlngs similar reference characters indicate corresponding parts in the sevcurb 17. The angle formed between the portions 15 and 16 comprises a chamber18 to receive water from drains 3 and groove 4 which pours out of holes 19 formed in the angle of portions 15 and 16. 7

surface of the roof and the cap pieces. At each side of the groove 4 the-beam 1s formed cushions for the plates of glass 7 forming but allow any water that might leak through The bottom rail of the supporting frame consists of a plate of metal having its base ends 10 maybe covered with solder 11. This construction-forming the abutments to The transverse bars consist of plates of metal each having a base with a ridge 21 formed by bending the plate longitudinally on a vertical plane as shown at 2a and and has its free edge curled upwardly to 1' form a gutter or drain 24 and 25, the drain 24L taking care of the water of condensation that forms on the inner surface of the glass plates, while the drain 25? catches any surface water that might leak through the joint above base 20, said drains delivering into drains 3 at each side of beam 1, the ends being bent downwardly as shown at 26 to form lips to prevent the Water from following the underside ofthe drain backwardly.

27 indicates a plate of sheet lead bent to engage the top of base 20 above ridge 21, the upper side of ridge 21 and the top of the upper edge of the plate of glass 7 below the cross bar.

The bolts 24 have their lower ends formed with a reduced rectangular portion shown at 28 to'fit rectangular holes in beam 1 and have their protruding ends riveted as shown at 30 to hold the bolts in position, this construction preventing the bolts from, turning when-screwing up the nuts 31 thereon that hold the caps 32 in place.

Caps 32 consist of plates of metal bent to form arch-shaped structures with their edges bent inwardly back on themselves as shown at 33 and then outwardly again as shown at 34, and have strips of lead or other soft metal 35 secured thereto by indenting the part 34:, as shown at 36, to engage said strips, the free edges of the strips extending outside of the edges of the cap 32 to form a watertight joint between the lower edge of the cap and the surface of the plates of glass 37 indicates putty or other soft filling i around the joints to exclude water and make Q a watertight joint.

Having thus described myinvention what 1. In a skylight, a supporting'beam provided with a' longitudinal drain or gutter and alined transverse slots, and an abutment plate having lugs engaging said alined slots and an arched portion between the lugs to span the drain or gutter.
